l Application filed November 13, 1916. Serial No. 131,159.

My invention. relates to change web roll.

mechanisms for printing presses and the like and it has .for its 'principal object/the provision ofa new and improved form and arrangement from a fresh roll in normal operative position upon its framework may be spliced to the web being fed tothe pressfrom another roll in another operative position upon the frameworkwithout the necessity for stopping or even slowing-down the press. `It is one of the objects of my invention to provide new and improved means for setting in rotation a fresh roll of paper preliminary to the splicing operation, such roll-rotating means being preferably located between the two rolls so as to be adapted to be brought into operative engagement with either roll as desired. It is another object of my in-V vention to provide anew and improved form of stripping mechanism which is adapted to be held out of engagement with a fresh roll to permit its free rotation, and then 'to be Ibrought into operative position relative to such fresh roll so asv to lstripthe leading .endl of the web from the roll, suitable guides being provided for directing the end of the web into Contact with the web being fed to -the press from the other roll; It is another 'object of my invention to provide a form of stripper mechanism comp-rising a plurality of Strippers adapted to be; brought into contact with a fresh roll near its uppermost part so as to extend between the body of the roll. and the end of the web for releasing n the weby from the roll and for supporting the web as it unwinds from the roll for directing such web toward the web being fed to the press from the otherv roll. It is another object of my' 'invention to provide means controlled by the sizeof the roll as it decreases in the printing operation for maintaining the strippers in the desired position relative tothe rollso as to prevent the strippers from interfering with 'the normal operation of the mechanism. It is another in Change Web-Roll cover by this application isset of mechanism by which the web object of my invention to improve mechanisms of this type in sundry details hereinclaims.

Referring toFigs. 1 to 6, in which corresponding parts are indicated by the same reference characters,-

lindicates a framelocated in a compartment or room below' the room in which aA printing press 16 is located. Rolls of paper 17-18 .are supported by' spindles 19-f-20,

respectively, mounted `in suitable bearings 31, 32 and 33, being further controlled by.

engagement in suitable grooves in a roller 34. (see Fig. 4) revolubly carried b the framework 15. The endless tape be ts 26- are supported at their upper ends by sheaves or pulleys 35 mounted upon a transverselyextending shaft 36, being supported at their lower ends by a grooved roller 37 4) which is in contact with the roller 34, the rollers 34 'and 37 being adapted to yield sufciently to permit the assage of the web -23 bet-Ween the rollers. dditional sheaves or pulleys 38 carried by a transversely-extendingvsllraft '39 bear upon the belts 26.

en the web is being fed to the press from a roll in either of-the two positions occupied by *the rolls 17-18, a fresh roll is placed in `position in the other position. Be-

fore the web is entirely exhausted from the roll in use, the end portion of the fresh roll is prepared substantiallv as shown in connection with the roll 17 in Fig. 2. In such preparation the end portion of the web is preferably narrowed toward its extreme end as shown in this figure, but that is not essential to the operation of the mechanism and -my claims are not' to be limited to such a preparation of the web except as hereinafter particularly -specified. The end portion .of the web vissecured to the body .of the roll by any suitable means which are adapted-to rele-ase the end readily upon the application of ajslight force thereto as hereinafter described. The means shown in the drawings are lin the form of stickers or which are preferably formed of light paper which is adapted to be torn readily across.

Paste or' gum of any suitable type is applied to the end of the web, as at 41, spaces being left between the gummed portions for contact of the tapes 24, 25 and 26 withthe web withoutcoming in contact with such gum. Other spaces are left for engagement with the periphery of the roll by the means by which-the roll is set in rotation preparatory to the splicing operation. The extreme end of the web is buckled outward between the Apasters 40- so as to permit' thel entrance of vstrippers as hereina ter Vdescribed between the end of the web and the body of the'roll.

pasters 40 VV-hen the web from one roll is substantial-lyv exhausted the other roll is to be set into rotation at the same surface speed as that of ing complete rotationof the fresh roll to pass between the end portion of the web and the body of the roll, serving to strip the end from the vroll for permitting the unwinding -of the web. The gummed end of the web of the fresh roll is then directed by the means hereinafter described into contact with the old web with which it is duly spliced and 'led through the press. When the gummed end of thev new web hasbeen pressed into 'contact with the old'web, the old web is to be torn across bv the hand of the operator or by any suitableA severing means which may be provided as desired.

The means forA rotating the f-resh roll, having its end portion gummed and secured releasably in position, comprises inthe construction shown a pair. of belts 42-43 which are adapted to be swung into contact with a' fresh roll in yposition upon either one of the spindles 19-20. The belts 42-43 are supported at their inner ends by sheaves 44 fixed 4upon a shaft 45 extending -across the framework 15. The outer ends of the belts 42-43 are supported by sheaves 46 which are revolubly mounted between arms 47-48 which are carried b sleeves 49 revolubly mounted upon the sha t45. The end sleeves 49 are adaptedto be rocked yby means of arms 50 extending outwardly therefrom, the outer ends of which 'are connected by means of links 51 and arms 52 with fa transversely extending shaft 53 which in turn is adapted to be rocked by means of a hand-lever 54. As is best shown in Fig. 3, the arms 47-48 for each belt 42-43 are connected by means of cross-bars 55-56 for bracing sucharms relative to .each other. In the construction shown, the intermediate sleeve 49 is not connected directly with the shaft 53, and itis believed thatnosucli direct connection is necessary, but it will be understood thatI do notrestrict my invention` in this respect. The hand lever 54 is adapted to be secured in either of three positions upon the rack 57, for holding the belts 42-43 in an intermediate neutral position so as to be out of contact with both rolls, or in an operative .position in contact with either an upper or a lower roll as desired.' Y

The Jshaft 45 is adapted to be rotated in either-direction as desired by means o-f a bevel gear 58 fixed upon one end of the shaft, meshing. with. bevel gears.' 59-60 l loosely mounted upon .a vertically-extending i shaft 61 driven from any suitable portion of 1,aoi,122

v42-43 lowered into contact therewith, the

gear 58 will be rotated in the opposite direction for driving such fresh lower roll in counterclockwise direction in said Fig. 1.

. The shaft 61 is driven constantly from the which a press at such a speed as to ldrive the belts 42-43 at the same surface speed as that of the web running through the press, serving thus to give the fresh roll in either position a similar surface speed.

Two sets of strippers are provided, one for a fresh roll in the lower position and the other for a fresh roll in thexupper position. The strippers of the lower set are indicated the numeral 64, being fixedly mounted upon a transversely extending shaft 65 about .which they are .adapted to swing. The shaft 65 is provided with a notched collar' 66 upon one end with which a latch 67 is adapted to engage for holding the shaft i 65 against rotation in clockwise direction in Figs. 1, 3 and 6, the arrangement being such that the latch 67 when in use serves to hold the strippers 64 in their uppermost position well out o'f contact with a fresh roll inthe lower position. The strippers of the upper set are indicated by the numeral 68, being ixedlymounted upon a shaft 69 about which they are adapted to swing. The shaft 69 is provided i latch 71 is adapted to engage for holdin the shaft against rotation in countercloc {wise direction in Figs. 1, 3 and 5, the arrangement being such that the latch 71 is adapted to hold the strippers 6,8 in their lowermost position well out of contact with g fresh roll in the upper position. A spring the shaft 69 tends to force the strippers l68 upward.

With a. fresh upper roll 17 in position having its end properly gummed and se-` cured by pasters, when the web from the lower roll 18 becomes substantially exhausted the clutch lever 63 is operated for setting the belts l2-43 in operation so as to move their upper portions toward the left in Fig. 1. The lever 54 is then moved to the limit of its motion toward the left in Fig. 1, lserving to swing the belts 42--43 upward into contact with the roll 17, .serving to set such roll intorotation at the same surface speed as that of the web 23. At the desired mouppermost the strippers l 'the belts 241-25 by which it is carrled upv with a notched collar 70 with;l

connected by means of an arm 73 with ment Ythe latch 71 is turned out of operative engagement with the notched collar 70, permitting the spring 72 to move the strippers 68 upward into contactwith the body of the rotating roll 17. When the buckled out end of the web of the fresh roll comes in the rotation f the roll to the position of the innermost stripper 68, -the stripper passes between the web and the body of the roll, tearin the pasters 40 in two for releasing the en of the web for unwinding. The new 'web thus released from the roll 17 is carried forward by its momentum along guides v74 which are supported in position by a crossbar 75. The end of the web is directedl by such guides into contact with the web 23, being pressed forcibly against the web 23 -between the rollers 34-37 for effecting a means, the spindle 20 is removed and a fresh `roll is inserted in the lower position after the strippers 64 have been 'raised to their osiftion where they are held by t'he latch 6 The endl of the web of the new roll, being the roll 76 shown in Fig. 3, is prepared substantially as shown in connection with the roll 17 in Fig. 2. At the proper time the roll 76 is set in rotation and the strippers 64 are released to strip the end ofk the'web from the fresh roll 76. The released. end of the fresh roll 76 is guided by 64 themselves into the bite of ward into contact with the web 7 7 being fed to the press from the roll 17, the rollers 454--37 again serving to complete the splicing operation by pressing the gummed end of the fresh web forcibly against the web running from the roll 17.

The means provided in the construction shown for controlling the position of the strippers 64--68 comprises a train of arms and links provided 'with rollers adapted to bear upon the rolls. The shaft 69 is provided with an arm 78 xedly mounted thereon which is connected by means 0f a link 7 9 with an arm 80 fixedly mounted upon a sleeve 81 from which depends an arm 82 which carries at its lower end a roller 83. As will be readily understood,.as the roller 83 is permitted to move to the right in Fig. 1 under the influence of the spring 72, the strippers 68 will be gradually raised so as to be `kept outof objectionable contact with the upper roll and out of contact with the web coming lfrom 'such roll. The means for controlling the strippers 64 comprises an arm 84 mounted upon the shaft 65 connec by means of a link 85 with an arm 86 fxedly mounted upon a. sleeve 87 upon which. 1s

arm 86 with a bracket 91 vextending" from` the frame 15, serving to hold the arm 86 v substantially jacent handle speed as that of web from the vroll yieldingly in its uppermost position.

In Figs. 7 and 8 which show a. modified form of construction, parts which correspondi to the construction above described are provided with the same reference characters butwith the addition of an exponent a. In this construction the strippers 64a direct the web from the lower roll directly into the bite of endless tape belts- 92-93 which are supported by means of sheaves or pulleys 94 mounted upon transversely-extending shafts 95 in suitable position. The guides 7ia direct the end of the webs stripped from the upper roll likewise to vthe bite of the same two sets of tape belts 592-93. The bevel gear 58a in the construction here showndis not fixed directly upon the shaft 45a, but is suitably connected with the roll-rotating belts through 'the medium of suitableiinterposed gearing. The means for swinging the roll-rotating belts comprises a 96 mounted directly upon the shaft ltl in lieu of the construction shown in Fig. 1 involving the lever 54 and the link and arm connection.

will be fu ly understood without giving a detailed description of thesame, inasmuch as it is in eect the same 'as that already described.

So far as I am aware,-I am the first in the' art to provide for supporting-a webv roll adto a` running vwebalnd' for rotating said roll independently of its supporting means substantially at the same surface the running web, means being provided for pleading'the end of the in either position into contact with the running web for securing said two webs together, and my claims are to be construed accordingly. It will be .understood that 1 do not Wish to be restricted to the details of the construction illustrated, except as hereinafter speciiically claimed, inasmu'ch as the construction can manifestly be changed in many ways witho ut departing from the spirit of my invention.
